The Russian Foreign Ministry said it has decided to expel a Bulgarian diplomat in a tit-for-tat move.
In a statement on Wednesday, the Ministry said it had summoned the Bulgarian Ambassador Atanas Krystin to inform him that an employee from the Bulgarian Embassy in Moscow has been declared "persona non grata", reports Xinhua news agency.
"The move comes in response to the baseless decision to declare a Russian diplomat persona non grata that Bulgaria made in April," TASS News Agency quoted the Ministry statement as further saying.
